Usually I'm searching aimlessly while thinking about something completely unrelated and I'm not bothering to be focused at all. The first step is to realize that I'm about to start looking for my keys in the same room for the third time and to stop and actually bother to focus and to bring the task to the foreground instead of the background.

Looking for my keys though is a minor annoyance and I'd rather be thinking about something else, so this isn't something I think needs fixing. It isn't driving a vehicle.
